Abstract (en)
[origin: EP2657631A2] The method involves mixing stream of carbon dioxide snow and carbon dioxide gas emerging from a carbon dioxide relief nozzle (5) after generation with a cold gas stream and cooling the mixed stream. The cold gas stream provided for cooling the stream of the carbon dioxide snow and the carbon dioxide gas is used for precooling liquid carbon dioxide before supply to the carbon dioxide relief nozzle. A partial stream of the cold gas stream is recirculated and used for cooling the stream of the carbon dioxide snow and the carbon dioxide gas from the nozzle. The cold gas stream is a cold cryogenic gas such as nitrogen, oxygen, argon and helium. An independent claim is also included for a device for cooling of products with dry ice particles.
